PARTY ON(40A. Repeated “Wayne’s World” cry … or a hint to each half of 17-, 26-, 51- and 63-Across),AFTER DINNER(17A. Kind of mint),HEN HOUSE(26A. Chicken coop),GREEN TEA (51A. Traditional Chinese beverage) and OFFICE BLOCK (63A. Multiple-company building, to Brits) constitute the interrelated group of this Tuesday crossword, rife with contemporánea.
